June 2006 - The University of Pennsylvania has increased the level of its green power purchases to 112 million kWh annually, representing nearly 30% of the school's annual electricity requirements. The wind energy will be supplied by Community Energy, Inc (CEI) from wind farms across the country. In 2001, Penn agreed to a three-year purchase of 20 million kWh from CEI sourced from Pennsylvania wind farms, which at the time was the largest retail purchase of wind energy in the United States. In 2003, the initial purchase was doubled to 40 million kWh under a 10-year agreement, also with CEI. The new five-year purchase makes Penn the leading green power purchaser among the nation's colleges and universities according to the U.S. Environmental Protection Agency's Green Power Partnership.
